Many have already suggested the use of a sinus-sweep.

the direction the reflections will come from. That way you avoid the near-f=

Last summer I did a quite'n'dirty impulse response from one of our hallways=

but using a sinus-sweep will give you better results both for natural sound=

impulse responses and for measurement purpose impulse responses.

Have fun,
